Scenario 3: Installing a Router in a Cabinet

Scenario 3: Installing a Router in a Cabinet


  • It is not recommended to install a Wi-Fi-capable router in a cabinet.
  • The AR100 Series, AR129CGVW-L, AR129CVW, AR129CV, AR169CVW-4B4S or AR169CVW router cannot be installed in a cabinet.
  • Leave at least 50 mm of clearance around the router for heat dissipation.
  • Seen from the front panel of the router, the airflow of the router is left to right.
  • If multiple routers are installed in a cabinet, it is recommended that at least 1 U of space (1 U = 44.45 mm) be kept between two routers. These routers must have the same airflow direction; otherwise, heat dissipation is affected by hot air circulation.

Make sure the following before the installation:

  • The cabinet is well fixed.
  • The router installation position in the cabinet is determined and arranged properly.
  • The router to be installed is available and located near the cabinet for convenient movement.

Tools and Accessories

  • Phillips screwdriver
  • Flat-head screwdriver
  • Floating nuts
  • Mounting brackets
  • M4 screws
  • M6 screws

The mounting brackets, floating nuts, M4 screws, and M6 screws are not included in the installation accessory package and need to be purchased separately.


  1. Use a Phillips screwdriver to fix the mounting brackets to both sides of the router with M4 screws.


    The mounting brackets can be installed on both sides close to the front panel or rear panel.

  2. Install two floating nuts on each front mounting rail. Leave a mounting hole between the two floating nuts on the same mounting rail.

    • The length of three adjacent mounting holes may not be 1 U. Observe the scale ticks on the mounting rails when installing floating nuts.
    • You can use a flat-head screwdriver to install floating nuts.

  3. Install the router into the cabinet.
    1. Use the Phillips screwdriver to install M6 screws on the two lower floating nuts, and leave 2 mm of the screws out of the floating nuts.
    2. Move the router into the cabinet with one hand supporting bottom of the router, and hook the mounting bracket on the M6 screws.
    3. Use the Phillips screwdriver to tighten the lower M6 screws and then the upper M6 screws.
